Hello tyankee, and welcome to the forums. I think we should all should take a few steps back and not think about Penguin in overly simple terms, such as keyword stuffing plus artificial backlinks. If that was all that's going on, it would have been a relatively simple tweak to the existing core algorithm. It's not that at all.
Penguin is another machine learning algorithm from Google, just like Panda was. It is computationally intensive and it does not run in "real time". In fact, there has only been one data refresh for Penguin to date, and the base algorithm has not been updated at all since the original launch.
All that points to a complex situation, and it is aimed at websites that rank well because of their "SEO" efforts compared to their user engagement. In contrast, Panda was aimed at demoting websites whose content was shallow or weak, but fell somewhere in between spam and a strong site.
It's not even clear to me what that difference is altogether, except that Pandalyzed sites were not considered webspam, and Google has labeled the sites Penguin targeted as webspam. What total combination of factors Penguin measures is not that clear, but I am certain that it is more than keyword stuffing plus backlink games.
Why would Google consider a well-ranked site to be "webspam"? How can we see a business we have labored over for years as spammy? That's a bitter pill! I'm sure it takes s kind of objectivity that is hard to come by for a site owner.
Have you considered asking a sampling of uninvolved people to look at the page that was ranking well and tell you if they would be happy with that as a #1 results?
